20150143853 | BUSHING ASSEMBLY COMPRISING A DISTRIBUTION MANIFOLD - The present invention concerns a bushing assembly comprising: (a) a liquid glass feeding unit arranged upstream of and in fluid communication with, (b) a first and second tip plate assemblies ( | 05-28-2015 |
20150051313 | TW PART SIZING COMPOSITION FOR COATING GLASS FIBRES AND COMPOSITE REINFORCED WITH SUCH GLASS FIBRES - The present invention concerns a two-part sizing composition comprising: (A) A precursor comprising: (a) An aminosilane (e.g. A1100) and (b) a polymer or copolymer containing carboxylic acid and/or anhydride, both having a functionality, F≧3, and (B) A binder comprising a multi-functional epoxy resin of functionality, F≧3. Glass fibres sized with the reaction product of the above composition yield a higher resistance to hydrolysis of polymeric matrix composite materials reinforced with such fibres. The sizing composition of the present invention is particularly advantageous for use with polyester resins, such as PET. | 02-19-2015 |
20140178685 | Sizing Composition for Charges Used in Thermoplastic Polymeric Material Reinforcement, Reinforced Polymeric Materials and Method of Manufacture - The invention relates to an aqueous sizing composition for reinforcing charges, preferably glass fibers, comprising a silane coupling agent, an epoxy film forming polymer comprising 2-8 reactive epoxy groups per chain and compatible with thermoplastic polyester matrix resin selected from PET and PBT, and a hypophosphite in an amount of 5 to 30 w % of the composition, preferably 7 to 25 w %, more preferably 10 to 20 w % and most preferably 12 to 18 w % of the composition. A thermoplastic polyester resin reinforced with glass fibers coated with a sizing composition of the invention shows improved resistance to staining and improved tensile elongation at break. The sizing composition further improves processability of the sized fibres. | 06-26-2014 |
20130193623 | Method and Equipment for Reinforcing a Substance or an Object with Continuous Filaments - The present invention provides a method of reinforcing a substance or an object with continuous filaments comprising the steps of (a) supplying a fiber strand from a source of fiber strands, (b) passing said fiber strand horizontally through a passageway ( | 08-01-2013 |
20130137565 | GLASS FIBRE COMPOSITION AND COMPOSITE MATERIAL REINFORCED THEREWITH - A glass fibre of quaternary composition including SiO | 05-30-2013 |
20130113133 | Impregnation Assembly and Method for Manufacturing a Composite Structure Reinforced with Long Fibers - The present invention provides an impregnation system suitable for impregnating filaments continuously with an impregnating substance, said system may comprise an impregnation assembly comprising (a) at least one axial passageway for the filaments having an entrance end and an exit end and (b) at least one passageway for the impregnating substance having at least one inlet for the impregnating substance and at least two outlets for the impregnating substance leading into the passageway for the filaments via the outlets for the impregnating substance, wherein the passageway for the filaments has an oblong cross-section at the outlet point for the impregnating substance, and the at least two outlets for the impregnating substance have an oblong cross-section, and are disposed essentially opposite to each other, at the opposite widths of the passageway for the filaments. Thus, the present invention proposes an in-line system for manufacturing continuous fiber reinforced thermoplastic structure which comprises a simple device to provide strands in spread filaments form without using high friction or tension on the strand or filaments so as to ease the impregnation step and to allow higher line speeds and lower cycle times. | 05-09-2013 |
